Adsorption of Vitamin E on Mesoporous Carbon Molecular Sieves

Hartmann, Martin, Vinu, A., Chandrasekar, G.·2005·Chemistry of Materials

Abstract

The adsorption of vitamin E onto mesoporous carbons CMK-1 and CMK-3 from vitamin E solutions with different concentrations in nonpolar ( n -heptane) and polar ( n -butanol) solvent has been studied for the first time, and the results are compared to a conventional microporous carbon adsorbent, activated carbon. The amount of vitamin E adsorption on the different adsorbents depends on the solvent as well as the mesopore volume and the surface area of the adsorbent. It has been found that n -heptane is preferred to achieve a maximum amount of vitamin E adsorption. Among the carbon materials studied, CMK-3 shows the highest vitamin E adsorption due to the large specific mesopore volume of this adsorbent. CMK-3 was characterized after vitamin E adsorption to confirm the structure of the adsorbent and prove that the adsorption takes place in the channels of the mesoporous carbon adsorbent. XRD and nitrogen adsorption data recorded after vitamin E adsorption confirm the tight packing of the vitamin E molecules inside the mesopores of CMK-3.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
